Have you ever tried to ONLY drink that shake as your entire daily caloric intake?
I guess what I'm looking for is something like a 'food pill' where all of my bodies needs are in this small, compact, simple pill or shake.
I must have misread your question "Can you survive only on meal replacement bars/shakes?"
When I made my post I didn't see the "only" part you wrote.
Sorry about the misunderstanding.
In answer to your question- No, I have not ever tried to drink a shake as my only source of calorie intake. I drink a shake only as a substitute but not on a regular basis. I have never heard of a pill or shake that can supply all
the nutrients the body needs.
